Muslim cleric Aboud Rogo was reportedly killed by three unknown assailants of Arab origin who were driving a white Subaru vehicle, the task force investigating the murder said.

Its chairman Jacob Ondari said two witnesses gave a description of Rogo's killers whom were seated in the back of the vehicle which drove off immediately. Rogo died in a hail of bullets as he, his father, his wife and one of their children were driving towards Mombasa from their home in Mtwapa.

"Descriptions have been given about the suspects.But so far we have not been able to pinpoint who exactly committed the act," said Ondari.

The witness statements may lend credence to claims that foreigners may have been involved in the murder of the cleric who was alleged to be having ties with the al Shabaab militia group.

However, the task force was unable to conclude whether the execution was done by the government agents, international interests or possible factions within the Al-Qaeda and Al Shabaab militia groups.

"We can only pursue the foreign angle of the murder if only it's brought to the knowledge of the task force by members of the public," said Ondari in Mombasa where his team is receiving testimony from the public. The team is due to present its final report to the Director of Public Prosecution Keriako Tobiko on January 16.

Two people have so far been charged with Rogo's murder while a third is still at large. The two have also been charged with arson, breaking, entering and stealing from a church.

Also in court is Abubakar Sharif alias Makaburi who is accused of inciting the week-long violence that rocked Mombasa soon after Rogo's death.
